Product information

Description

Onnline radiator reducer B-695529 5/4 x 1/2" right is a threaded adapter designed to connect radiator valves and pipe fittings with different thread sizes. The reducer provides a right-handed step-down from 5/4" to 1/2", enabling a secure mechanical connection in central heating and hot-water radiator installations where size adaptation is required.

Advantages

The adapter offers a compact and robust solution for changing thread diameters without modifying existing valves or piping. Its threaded design ensures reliable mechanical engagement and leak-resistant performance when installed correctly. The simple geometry and smooth threads allow for quick installation and removal, minimizing downtime during maintenance or component replacement.

Подходит для

  • Подключение радиаторных кранов к трубопроводам с меньшим диаметром
  • Замена или адаптация фитингов при ремонте отопительной системы
  • Временные или постоянные решения для соответствия резьбы разных узлов

Key specifications

  • Thread connection: right-handed (step-down)
  • Inlet size: 5/4"
  • Outlet size: 1/2"
  • Function: threaded reducer for radiator valve connection
  • Typical application: central heating and radiator piping

How to use

Ensure the mating surfaces and threads on both the radiator valve and pipe fitting are clean and free of debris. Wrap appropriate thread sealant tape or apply a compatible thread sealant to the smaller thread as recommended for your system. Screw the adapter into the larger valve thread by hand to start, then tighten with an appropriate wrench until secure, taking care not to overtighten and damage the threads. After installation, pressurize the system and inspect the connection for leaks; retighten slightly if necessary following manufacturer guidelines for sealing materials.

Usage recommendations

Use compatible sealing materials (PTFE tape or liquid thread sealant) rated for heating systems. Avoid excessive torque to prevent thread damage. Verify material compatibility with the medium and operating temperatures of your heating system before installation.
